FEED-REGULATOR FOR MILLS.

Specification of Letters Patent.

Patented Nov. 23, 1915.

T0 @ZZ whom t may concern.'

Be it known that I, Lucius FREEMAN IiirrLn, a citizen of the United States, residing at Owensboro, in the county of Daviess and State of Kentucky, have invented new and useful Improvements in Feed-Reg-` of filling the break rolls with an overflowl of grain when the mill is not in operation is entirely done away with, and an even and normal distribution of grain will be maintained while the mill is running, and choking of theV rolls during stoppage of the mill is eliminated.

I have illustratedmy invention in connection with a well known type of roller mill, in which the grain to be reduced is fed from a suitable hopper to the break rolls, and thence, as is usual, to suitable bolting and reducing instrumentalities.

In the drawings accompanying and forming part of this specification, I have illustrated only so much of a conventional mill as is necessary to an understanding .of my invention, and in said drawings- Figure 1 is a side elevation of a portion of a mill with my feed mechanism attached thereto. Fig. 2 is an enlarged plan view of the feed mechanism which I have invented. Fig. 3 is an enlarged front View of the feed mechanism shown in the other views.

Referring to the drawings by numbers, like numbers indicating like parts in the several views, 10 indicates a mill of any suitable type having a hopper at its top from which the grain is fed to the reducing instrumentalities within the mill casing.

Mounted in the mill is the feed board 11, which comprises the feed pocket 12, and the inclined feed board 13 which delivers to the break, conventionally shown. The said feed board 11 is oscillated by any suitable mechanism, as for example the eccentric 14E vand thrust rod l5, so as to agitate the contents of the feed pocket 12, and cause it to flow in a regular stream over the inclined board or screen 13, as is not unusual in this type of mill. The said feed board 11 is provided with a pair of bracket arms 16 projecting' upwardly therefrom, and securely fastened at their lower ends by means of suitable fastening means, such as bolts and nutsl?, so that the said bracket arms partake of the motion of the feedboard as it is oscilw lated by the mechanism just described. Mounted upon the said bracket arms 16 is a regulator board or feed-controlling plate 18, this board .being slightly inclined with its delivery end overhanging the feed pocket 12, the said regulator board being closed at its backand sides, as shown in Fig. 1, and preferably it will be adjustably mounted by means of the bolts 19 adjustable in slots 20 formed in the bracket arms 16. The said regulator board is mounted just beneath the feed hopper 21, which may be of any suitable design, and the lower end of which will be in proper feeding relation to the board 18, so that `the stream of grain will readily ow from the hopper 21 onto the regulator board 18, and thence vfall to the feed pocket 12, from which it will flow down the feed board 13 to the mill. f

It will be obvious that as the feed board 11 is oscillated the feed regulator board 18 will partake of those oscillations, and the stream of grain from the hopper being constantly agitated will flow readily and keep up a continuous delivery of the grain to the mill. Immediately the operation of the mill is stopped however the feed regulator 18 will come to a state of rest, and the stream of grain flowing from the hopper will be no longer agitated, but immediately the board 18 comes to a state of rest the grain will be choked back and its fiow discontinued, the excess of How simply spreading over the board 18 to a slight extent without any undue loading of the feed pocket 12, and a consequent excess on the board or screen 13 or objectionable flow from said board 13 to the reduction rolls. Immediately the mill starts the board 18 will begin to deliver to the feed pocket 12, and the flow from the hopper 21 will be resumed.

The regulator board 18, it will be observed, is adjustable both vertically with respect to the hopper and angularly by means of the bolts 19 and slots 20, so that a greater or less inclination may be given to it to secure the proper angle to insure the choking back of the grain in the hopper and avoidance of the flooding of the main feed bOard upon stoppage .0f the mill, the area Y 1tv of the board 18 vbeing figured out so as to give a suiiicient capacity to take care of the flow rfrom the hopper, and secure the proper choking' back of the grain.

Bymeans of thissupplemental regulator board in conjunction with the ordinary feed board I am enabled to very effectively control the flow of grain from the hopper and maintain always a normal cnditionof the grain in the feed pocket l2, and on the main feed board 13, so that there is no likelihood ofiiooding* thekmill during stoppage, nor is vthe. regular feed board loaded to excess so that vupon starting an abnormal quantity of grain isdeliveredto the reduction rolls.

It `will be understood that structural departures may be made from the apparatus here shown, and I do not, therefore, limit myself to the particular embodiment of invention herein setV forth.
